MANUFACTURE OF HORN BUTTONS.

SPECIFICATION forming part of Letters Patent No. 224,399, dated February 10, 1880.

Application filed December 19, 1879.

Heretofore in the manufacture of such but tons the tip or solid portion of the horn has only been used for finest buttons by cutting the same across the grain of the horn, and to some extent the sides of the horn have been used; but the latter gives a button of inferior appearance on account of being cut in the direction of the grain. 1

My invention consists inmaking the button from the hollow portion of the horn. by cutting the same transversely into rings and fillin g the center of the ring with a disk cut from the tip or side of the horn, thus giving a button which presents the end grain on the surface of the ring, and on the center also, when the tip is used for filling.

This method will be more particularly de scribed with reference to the accompanying drawings, wherein- Figure l is a cross-section of the button in its complete form. Fig. 2 is a similar view of v the two pieces as cut from the horn.

Similar letters of reference indicate corresponding parts.

The button A is formed of the ring portion a and filling-piece b. The ring ais obtained by cutting across the hollow portion of the horn, while the filling-piece b is a disk cut aperture in ring a.

' from the tip or solid part of the horn or from the sides. To connect these parts together they are first turned smooth, the piece 12 being left of slightly larger diameter than the The ring a is then heated to expand it, preferably by dipping in hot oil, the piece b inserted in the ring, and the contraction of the ring when cool will retain the center firmly. The button is then to be finished by turning and polishing.

Thering b, being out transversely of the grain, presents the end grain on the surface similarly to the center-piece when that is out from the tip, and in case the center-piece is cut from the side of the horn a handsome contrast is given, which appearance will be made more striking by having the center-piece of a darker shade of the color.

It will be seen that the buttons may be made of any desired size by cutting the rings from different portions of the horn, and as the hollow portion of the horn is larger than the solidportions generally used for buttons, larger buttons can be made.

The button made in this manner is cheap
